Metodologia de controle de custos em obras

Para o sucesso de um empreendimento de uma construção civil é necessário que se faça um rígido controle de todas as etapas que envolvem o projeto. Com isso, o gerenciamento de custos torna-se um fator decisivo para o sucesso do mesmo. O desenvolvimento de um orçamento conciso, que contemple todos os serviços necessários para a execução do empreendimento, faz-se necessário para evitar perdas e atrasos no cronograma físico-financeiro da obra. Uma vez com a orçamentação realizada, cabe à equipe técnica, que irá executar a obra, estabelecer um controle de custos que garanta com que o custo real da obra permaneça o mais próximo possível do orçamento planejado. Gerir custos através das boas técnicas fará com que o resultado final fique mais próximo do planejado. Ou seja, se os processos para o controle de custos forem negligenciados, a empresa terá perdas financeiras, clientes descontentes e perdem o reconhecimento profissional, dentre outros problemas. Para o sucesso final de qualquer empreendimento, é necessário que o engenheiro tenha conhecimento de gestão de projetos e de pessoas, bem como uma equipe de trabalho alinhada as diretrizes da empresa, fazendo com que tudo o que foi definido durante o planejamento da obra seja executado com total coerência
